Electromagnetic Firepower with a DIY Coilgun

Electromagnetism packs quite a punch. Coil guns, like the one pictured above, use electromagnetic coils to push a ferromagnetic projectile rapidly through a barrel. The electromagnetic current is usually drawn from a battery and controlled with capacitors. Learn how to build you own coil gun in this project:

The physics behind it is actually pretty simple and the entire thing can be build from common parts. The outside of the coilgun is finished with housings made from plexiglass, wood and metal.

This DIY Coilgun project features a complete rundown on the schematics and physics behind the gun. Don’t forget to catch the two videos in the tutorial as well. This coilgun just another addition to the arsenal of the hobbyist who loves DIY projectiles.
